A USB HID Joystick is connected to my STM32F401-based board. I used last versions CubeMX, the USB_HOST library, and HAL. Everything works automatically with the mouse and keyboard, but not with the joystick. I made the following changes in the library based on USBlyzer data:
usbh_conf.h
/*---------- -----------*/
#define USBH_MAX_NUM_ENDPOINTS 1U
/*---------- -----------*/
#define USBH_MAX_NUM_INTERFACES 1U
usbh_core.c
I commented out all sections of the code with the creation of the IN pipe
phost->gState = HOST_ENUMERATION;
phost->Control.pipe_out = USBH_AllocPipe(phost, 0x00U);
// phost->Control.pipe_in = USBH_AllocPipe(phost, 0x80U);
/* Open Control pipes */
// USBH_OpenPipe(phost, phost->Control.pipe_in, 0x80U,
// phost->device.address, phost->device.speed,
// USBH_EP_CONTROL, (uint16_t)phost->Control.pipe_size);
/* Open Control pipes */
USBH_OpenPipe(phost, phost->Control.pipe_out, 0x00U,
phost->device.address, phost->device.speed,
USBH_EP_CONTROL, (uint16_t)phost->Control.pipe_size);
usbh_hid.h
Add nonboot code for my joystick
/* Interface Descriptor field values for HID Boot Protocol */
#define HID_BOOT_CODE 0x01U
#define HID_NONE_BOOT_CODE 0x00U
#define HID_KEYBRD_BOOT_CODE 0x01U
#define HID_MOUSE_BOOT_CODE 0x02U
usbh_hid.c
Add
else if (phost->device.CfgDesc.Itf_Desc[interface].bInterfaceProtocol == HID_NONE_BOOT_CODE)
{
USBH_UsrLog("Non boot device found!");
}
Changed the protocol to non-boot
case HID_REQ_SET_PROTOCOL:
/* set protocol */
classReqStatus = USBH_HID_SetProtocol(phost, 1U);
if (classReqStatus == USBH_OK)
{
HID_Handle->ctl_state = HID_REQ_IDLE;
My code goes as far as getting the USB_HID_GetHIDReportDescriptor in the USB_HID_ClassRequest function and gets it. But then it breaks down on the USB_HID_GetReport function in USB_HID_Process, where I always get the status USB_NOT_SUPPORTED. I need to get a report, my functions will process the data, but I can't get a report and really don't understand why.
Therefore, I need your help, maybe someone has already worked with similar HID devices and USB_HOST library.

I have written a small 6502 program to loop through memory and use STA Zero Page Indirect Addressing to store a value in 128 consecutive memory locations, but the program doesn't appear to be working. It should store 128 copies of the value $01 to memory address $0400 on-wards but it does not. What am I doing wrong?
*=$8001
; set $00,$01 to $0400
LDA #$00
STA $00
LDA #$04
STA $01
CLC ; Clear carry and decimal mode
CLD
LDX #128 ; Loop 128 times
LDY #0
loop LDA #$01 ; the value to store
STA ($00),Y ; store A to the address held in $00,$01
; Add 1 to $00,$01 (16-bit addition)
LDA $00
ADC #1
STA $00
LDA $01
ADC #0
STA $01
; do it 127 more times
DEX
BNE loop
RTS
It looks like you're incrementing the value stored at $00, but shouldn't you be manipulating Y instead? Something like:
*=$8001
LDA #<$0400 ; store $0400 into $00 and $01
STA $00
LDA #>$0400
STA $01
LDY #128 ; load 128 into Y
LDA #$01 ; load 01 into A
loop DEY
STA ($00),Y ; store A into $0400 + Y
BNE loop ; loop until Y is zero
RTS
In this loop, we get rid of X, initialize Y to 128, and then decrement Y for each loop iteration. This means we're filling memory "backwards".
Note 1
Addresses $00 and $01 are often special (e.g.,
on the C64 these addresses control processor features), so depending
on your environment you may need to choose different zero memory
locations.
Note 2
If I were writing this, I would avoid hardcoding addresses directly into the code, and instead declare a named storage location. When testing your code locally, I assembled it using 64tass and the following code:
*=$00fb
addr .word ? ; declare two bytes of storage at * and *+1
; I'm using $00fb because this is an unused zero
; page location on the c64 (and I'm testing using
; the VICE emulator).
*=$8001
LDA #<$0400 ; store $0400 into addr and addr+1
STA addr
LDA #>$0400
STA addr+1
LDY #128
LDA #$01
loop DEY
STA (addr),Y
BNE loop
RTS
Update 1
Your original code seems to work just fine for me. Note that when testing in a C64 emulator, the range $0400-$0480 corresponds to the screen memory (see e.g. this memory map), so when returning to BASIC, that range is overwritten. For example, with your code loaded at $8001, I see the following code in the monitor (assuming we're storing the address in $FB and $FC):
(C:$e5cf) d 8001
.C:8001 A9 00 LDA #$00
.C:8003 85 FB STA $FB
.C:8005 A9 04 LDA #$04
.C:8007 85 FC STA $FC
.C:8009 18 CLC
.C:800a D8 CLD
.C:800b A2 80 LDX #$80
.C:800d A0 00 LDY #$00
.C:800f A9 01 LDA #$01
.C:8011 91 FB STA ($FB),Y
.C:8013 A5 FB LDA $FB
.C:8015 69 01 ADC #$01
.C:8017 85 FB STA $FB
.C:8019 A5 FC LDA $FC
.C:801b 69 00 ADC #$00
.C:801d 85 FC STA $FC
.C:801f CA DEX
.C:8020 D0 ED BNE $800F
.C:8022 60 RTS
If I place a breakpoint at $8022 and tune the code...
(C:$8029) break 8022
BREAK: 1 C:$8022 (Stop on exec)
(C:$8029) g 8001
#1 (Stop on exec 8022) 064 011
.C:8022 60 RTS - A:04 X:00 Y:00 SP:f2 ..-...Z. 4131803
And then inspect the target memory range, it's filled with $01:
(C:$8022) m 400,480
>C:0400 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 ................

But as soon as I return to BASIC, it looks like this:
(C:$e5d4) m 400,480

Mainly, I'd like to obtain a df (data_final) with one row for each t (for each ID), and the proper status X.
Any idea?
I'm learning C and as a practice, I'm trying read a file with different sets of numbers in each line, and print (or save to a different file) each number per line (also as string).
You can see the code here:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define SIZE 40
int main(){
char numbers[SIZE];
FILE *fileRead;
FILE *fileWrite;
char *token, *tofree, *str;
fileRead = fopen("/Users/USER/Documents/readfile.txt", "r");
if (fileRead==NULL){
printf("File not found\n");
return 1;
}
fileWrite = fopen("/Users/USER/Documents/writefile.txt", "w");
if (fileWrite==NULL){
printf("File not found\n");
return 1;
}
while (!feof(fileRead)){
fgets(numbers, SIZE, fileRead);
tofree = str = strdup(numbers);
while ((token = strsep(&str, " \n"))) fprintf(fileWrite,"%s\n", token);
free(tofree);
}
puts("Succeed");
return 0;
}
When I remove the '\n' character at printing/writing, all the numbers are printed one after the other. I expected that.
The problem is that when I include the \n char, the output includes some empty lines. I include an example of the input and the output files:
Input:

As you can see, the output includes an empt line when the original file had a newline, but if I remove the \n, it prints/writes just one number after other without space:

What character is being inserted if \n is an explicit delimiter?
I had a problem with an index. The index name is "dbo.indexname" (including '"') and I cannot delete it. Someone knows how to drop an index with that name?
sp_help table output:
index_name, index_keys, index_description, index_max_rows_per_page, index_fillfactor, index_reservepagegap, index_created, index_local

What is the name of the table? Let's assume 'mytab'.
Now do this:
set quoted_identifier on
go
drop index mytab."dbo.indexname"
go
