Hi,We have a STM32L031F6 which is used as an RTC. A weird phenomenon is occurring: when the controller goes to sleep, it only uses 2µA, but after 2 minutes and 40 seconds, it starts consuming 50 to 100µA, depending on the hardware board used. There i...

Hi,I need a DMA setup for 4 separate UARTs in an STM32G473 controller. The idea is to always be able to receive data through rxDMA, and only invoke txDMA when sending data. The data that I receive changes in size, is between 20 and 300 bytes, starts ...

Hello,I'm currently working with a custom board designed to read digital values from an accelerometer, specifically from the OUT_X, OUT_Y, and OUT_Z registers. However, I've encountered an issue: despite the accelerometer being physically stable, I a...

Hello,I have developed an application that saves accelerometer data when a machine starts up. This data is stored in the last page of the controller's memory (page 31).I'm encountering a HardFault exception that occurs intermittently, roughly 1 in 20...

Hi,My Controller is STM32G473RE . Sample rate is each 2.8 ms .I have created a filter with mathlab which presented me with plain C code.This code does exactly what i want and gives the expected results.int16_t input[3100]={4582,4581,4573,.... double ...

Unfortunately, I don't have the time to thoroughly investigate the HAL code.In other developments, I noted that HAL functions are not always working 100% reliably, so we tried the lower layer functions instead.Nonetheless, HAL remains a huge speed bo...

It appears that the issue was related to the code in the HAL libraries. To resolve it, I made the following changes:Instead of:__HAL_ADC_ENABLE(&hadc);I now use:LL_ADC_EnableInternalRegulator(ADC1); LL_ADC_Enable(ADC1);And instead of:__HAL_ADC_DISABL...

Boot0 -> 10k to GNDPB1 is configured as output low.SWDIO and SWCLK just go to the debug connector and do not have Pull Up or Down configuration in ioc

as you can see in the schematic, the inputs need to be used as intrusion event, and are pulled up with a 1M5 resistor.
