ChibiOS Free Embedded RTOS

I realize this is an old post, but it looks like the OP is declaring the class as a local variable in main() which puts it on the stack. Unless the stack is made large (for main, that's defined in chconf.h), this will be an issue regardless of the SRAM size. Consider making the classes static, which ...

On my STM32L152 project, I'm using one of the I2C units in master mode at 100 kHz in a PMBUS application (talking to a PMBUS compatible power supply). All communications with the I2C is in a single thread. I found that on some occasions, my firmware was locking up, usually when other threads ran in ...

Hello Giovanni,
Thank you for the quick turnaround. I did a git pull today and noticed that there was a patch to os/hal/ports/STM32/STM32L1xx/hal_adc_lld.c. Looks like there was a change, but the write is to the wrong register: ADC_SQR1_NUM_CH(grpp->num_channels) is being written to SMPR1 instead of ...

I added STM32_EXTI_REQUIRED to my halconf.h, even though this is normally something that's used by device drivers. After that, instead of directly writing the EXTI registers as I had previously, I could call

extiEnableLine(22, EXTI_MODE_RISING_EDGE | EXTI_MODE_FALLING_EDGE | EXTI_MODE_ACTION ...

Thank you Giovanni, I looked up the relevant information in the EXTIv1 peripheral and wrote the following:

#define STM32_COMP_NUMBER 22
#define STM32_COMP_HANDLER Vector98
OSAL_IRQ_HANDLER(STM32_COMP_HANDLER)
{
OSAL_IRQ_PROLOGUE();

/* Clear the pending IRQ by writing a 1 */
EXTI->PR |= ~(EXTI ...

I wish to use the COMP peripheral in an STM32L152RE to generate an interrupt. From other posts on the forum, I had found out about ChibiOS-Contrib, and the existence of a COMPv1 peripheral there. It looks like that LLD does not support the STM32L152 (it's meant for L0xx devices). I'm able to ...

I think there's a bug in the STM32L1xxx device-specific ADC HAL driver.

When doing a multi-channel conversion in a sequence, only the first channel was getting converted. For example, I had a conversion group with num_channels = 4, SQ1 = CH4, SQ2 = CH8, SQ3 = VREF, SQ4 = SENSOR. When I run ...
