rxBuf is uint8_t array. // this creats HardFault sometimes: id = *(uint32_t *)&rxBuf[i]; //---------------------------------------------------- // but this works OK forever: id = rxBuf[i + 3]; id <<= 8; id += rxBuf[i + ...
What happened to the equivalent of I2S_FLAG_CHSIDE as I don't seem to be able to find it.Or do you just count the interrupts and assume it goes Left - Right - Left... forever?ThanksAndy.
Where can I find the default values for the option bytes? I'm using a STM32L151CCI mean the option byte values stored in the factory on delivery.
Hi,I recently need to use I2C with interrupt mode to lower my CPU usage.So I did this changes :I changed the function where I call my transmitstatic HAL_StatusTypeDef PGA309_Write_RawData(uint8_t REGISTER,uint8_t LSB_DATA,uint8_t MSB_DATA) { uint16_...
A bit confused by STM32L496 DISCOVERY board.Documentation says Arduino compatible connector maps timer functions like following printscreen.But in CubeMX, the pins are very different, as can be seen on the following printscreens.E.g. Discovery board ...
Datasheet and Reference Manual have contradictions about the LSI Power.Information from Datasheet:The RTC is functional in VBAT mode and in all low-power modes when it is clocked by theLSE. When clocked by the LSI, the RTC is not functional in VBAT m...
Hi all, I am a new STM32 user migrating from Atmel/Microchip's SAMD line. I created my first project following along the tutorials here: https://www.youtube.com/watch?v=x_5rYfAyqq0&t=682s.It's a motor driver, with some other hardware shown outside of...
I have a STM32G431 MCU board and TIM8 is triggered by an external input pin to perform a counter capture and initiate a DMA transfer for CH1. What I would like to also do on TIM8 is perform a counter capture based on a software trigger to CH3. Is thi...
I'm working on a bootloader which needs to erase and program the Flash. The erase seems to be 'working' but I have a suspicion that I'm not waiting long enough for the 'Busy' bit to go active after setting the 'Start' bit. The reference manual says I...
