Resolved! Scatter file issue - does RESET have to be located at the base flash address?
I'm somewhat new to scatter files and I'm trying to understand them better by doing some tests on a ST32F765 project (with 2mb flash at 0x0800 0000 - 0x081F FFFF).This scatter file works OK:LR_IROM2 0x08100000 0x00100000 { ; load region size_regi...
I wonder why this creates HardFaultError rarely and randomly. Thanks
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 + ...
Resolved! SAI in SAI_I2S_STANDARD Mode...
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 STM32L151CC
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.
Resolved! STM32H743ZI I2C4 unexpected interruption
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_...
Resolved! Bug in documentation of timer outputs in STM32L496G Disco board?
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 ...
LSI in Backup Domain on STM32H735.
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...
Resolved! STM32F302R8 unable to use GPIO
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...
