Please help advice.
I am fighting several days with option ADC.
I am using 2 channels ADC IN0 and IN1 on STM32L010RB microcontroler via HAL library.
If checking apart then everything are good but when I am checking together it I have all time the same problem: first channel rewrite data on second channel and I have the same data on IN0 and IN1 in terminal
Function for select IN0.

I am working with an stm32 f767zit and I am trying to generate PWM signals to control servos, but they are not generating correctly. I followedd the tutorial from here Deep Blue Embedded and was able to generate the PWM signals just fine on an stm32 f103rb, but I switched to the f767zit because I needed more PWM outputs. I have already looked at the HAL documentation and for both and compared them and as far as I can tell there are not any differences in how the pwm signals should be generated.
I have done several projects with the stm32 boards but I am still sort of a noob. I have looked for many hours for a solution but I can not find one. Sorry if this is actually just something simple and basic that I am missing.
Here are screen shots of the pwm outputs. as you can see the f103rb generates them normally, sguare waves at 50hz and 3.3v peaks. The pwm signals on the f767 are made up of lots of spikes and have peaks at 10mV. Although, they do seem to be generating at the correct pulse length
PWM Output of f103rb
PWM Output of f767
In my code all I am trying to do is initalize the servos and the set them to a positon. There are 12 servos and they are using timers 1-4. The specific channels and pins can be seen in the Servo configuration code. My main code initializes all of the perifrials and then calls initServos() which calls SERVO_init() for each servo in SERVO_CfgParam. Then my main loop calls SERVO_moveto(). I am only moving one servo in the main code but I have tested every pin that I am using and get the same results.
I used the same meathod and code for controlling 3 servos on my f013rb without any problems. I cannot figure out what difference there is on the f767zit.

Let me know if there is any more information that you need.
I think your problem might be due to the alternate function mapping. The F767 datasheet has a table on p.89 listing what values you should put into the GPIOn.AFR registers (GPIO_InitStruct.Alternate in the HAL - I assume) to get the right peripheral on the pin. It looks like your timer channels for those pins are all AF1, and you haven't defined which AF to use in your SERVO_Init routine. It's probably a good idea to fill in every member of the struct, even if you think it's unnecessary, just to make sure you don't miss anything deceptively important.
I'm working on the ADC , conversion triggered by timer2 , but there is no output. APB2 Timers clock is 80Mhz. Only 1 ADC channel. ADC clock is also 80Mhz. ADC conversion is triggered by 3.3us. Controller is STM32L452. Ignore Timer3.
Please let me know where I'M WRONG.

firstly htim2.Init.Prescaler = 0; try to give any number but 0 to prescaler to receive interrupt htim2.Init.Prescaler = 1 or 2 or else;
Secondly in your callback you are checking timer 2
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
if (htim->Instance == htim3.Instance)
{
/* Toggle LED */
HAL_GPIO_TogglePin(DEBUG_LED_GPIO_Port, DEBUG_LED_Pin);
}
}
I propose you to check timer2 because you are initializing the timer2 in your code which is //HAL_TIM_Base_Start(&htim2);
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
if (htim->Instance == TIM2)
{
/* Toggle LED */
HAL_GPIO_TogglePin(DEBUG_LED_GPIO_Port, DEBUG_LED_Pin);
}
}
I have got a problem with the development of a i2c communication between a ATMega328 and a STM32 F302R8 controller.
Below the initialisation code of the st controller, generated by Cube.
void MX_I2C2_Init(void) {
hi2c2.Instance = I2C2;

if (i2cHandle->Instance == I2C2) {
/* USER CODE BEGIN I2C2_MspInit 0 */
/* USER CODE END I2C2_MspInit 0 */
/**I2C2 GPIO Configuration

GPIO_InitStruct.Pin = GPIO_PIN_9 | GPIO_PIN_10;
GPIO_InitStruct.Mode = GPIO_MODE_AF_OD;
GPIO_InitStruct.Pull = GPIO_PULLUP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF4_I2C2;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
/* I2C2 clock enable */
__HAL_RCC_I2C2_CLK_ENABLE()
;
/* USER CODE BEGIN I2C2_MspInit 1 */
/* USER CODE END I2C2_MspInit 1 */
}
}
I added the HAL_I2C_MspInit(&hi2c2); call for setting the pins in the right mode.
The Function SerialMain part of a thread and will be called regularly.
void SerialMain(void const* arg) {
MX_USART1_UART_Init();
MX_I2C2_Init();
char *buffer = "Hello World! ";
int cnt = 0;
for (;;) {
cnt++;
if (HAL_I2C_Master_Transmit(&hi2c2, 8 , buffer, 13, 1000) != HAL_OK) { //PA9 SCL PA10 SDA
SerialError();
}
if (HAL_I2C_Master_Transmit(&hi2c2, 8 >> 1, &cnt, sizeof(cnt), 1000)
!= HAL_OK) { //PA9 SCL PA10 SDA
SerialError();
}
osDelay(10);
}
}
After trying to transmit the Hello World message the HAL_I2C_Master_Transmit will return HAL_TIMEOUT.
Does someone know why it returns HAL_TIMEOUT?
Does someone know how to transmit data successfully?
I'm trying to do a kind of "terminal" interaction with my STM32L476.
First of all I want to do a direct echo, when I recive data send it back for the same UART.
After, I want to put the echo in a task.
Question:
I'm implementing a hard-real time OS and want to leave UART operations to IDLE task, or very low priority task.
Is this a good way of doing things?
I can print using:
void uartPrint(UART_HandleTypeDef *huart, char _out[]){
HAL_UART_Transmit_DMA(huart, (uint8_t *) _out, strlen(_out));
}
But I don't receive, or the HAL_UART_RxCpltCallbackis not called never.

I'm not using yet the uart task, but here is where I create the task at freertos.c
osThreadDef(uartTask, UartTask, osPriorityNormal, 0, 128);
uartTaskHandle = osThreadCreate(osThread(uartTask), NULL);
The Uart Init: appears on my terminal.
When I debug, program never reaches the HAL_UART_RxCpltCallback.
Thanks!
