Posted on January 30, 2014 at 08:24 There is a bug in CPAL_I2C_IsDeviceReady that prevents it from ever returning failure. /* wait until timeout elapsed or target device acknowledge its address*/ while ((__CPAL_I2C_HAL_GET_ADDR(pDevIn...
Hello,I'm commucating two STM32 F4 boards using SPIThe first board is configured as a Master and used to only transmit data #define message_tx_size 4 uint8_t message_tx[message_tx_size] = "ABCD"; .... int main(void){ while (1){ HAL_SPI_Transmit...
Hi,I work with STM32F412ZG processor. I have also external LSE. I have the next problem related to STOP mode. There are some scenarios we want the processor to go to sleep for x hours. The processor goes to sleep for 5 seconds, doing some job and ret...
Hello,What are physical conditions to get bkpsram in stm32f405 changed?I got cases, that during controller work vbat domain sram was changed.I don't know if whole memory was changed. I'm using some part of it, but also rtc memory was changed. Where a...

Hi, I use an stm32f429 discovery board to examine some exercises.When I enter debug mode, SWV error message appears.That message appears today, not until yesterday, but I didn't change any settings.error messageFailed to enable SWV.SWV will be disabl...
After finding that the stm32u5 series seemed perfect for my application I discovered it does not have an FMC SDRAM controller.This leaves me in a strange position for my application where the stm32h5 doesn't have HS USB and the stm32u5 doesn't have a...
Hi,Currently we are using STM32 CAN bootloader to program the flash. All was fine until we use this batch of STM32F405 RGT6 with bootloader ID V3.1.We can not even use STLINK-V3SET and stm32cubeprogrammer to get communicate to this batch of chip. Rea...
Hi, I need to use the MCP79410 rtc (or alikes: DS1307, PCF8583, etc) but the STM32CubeIDE I2C seems that can't handle the read/write protocol for these devices. For example, as the below image shows, one needs to send the control byte (writing) follo...
I'm working with an existing CAN network on which I want to read a msg, modify it slightly and rebroadcast.I'm running into an issue where the code seems to crash/freeze if I broadcast the new message too close to the original one thats on the networ...
