Hello everyone,I have created a project with STM32L151CBU and used UART2 (PA2, PA3) for communication with some other transceiver IC.I have configured my UART as follows for (1-bit start, 8 bits data, 1 bit EVEN parity, and 1 bit stop) communication....
Hi everyone, hope everyone is doing wellI am trying to setup the STM32H743ZI's ADC for a 5 channel Continuous scan. The 5 scans will be used forThe Input voltage - Channel 0The Input Current - Channel 1The output Voltage - Chanel 2The output Current ...
Hi all,I am working with a Nucleo STM32L452RE board and I had a bit of trouble enabling the RTC clock. I am just trying to get a scope shot of the waveform output by the clock itself and I noticed it was not on by default. I attempted to use a few ex...
I am chasing reason the for last 4 mA of current that my 32F413 microcontroller draws during low current shutdown. By "shutdown" I mean sleep mode where my system is powered from a small battery with short life.A really good engineer would have equi...
I am currently attempting to port a product's older firmware that used the Standard Peripheral Driver libraries over to using the HAL libraries for greater portability between different MCUs. I a currently using the STM32L151QEHx. In the older firmwa...
I am designing a PCB for an ST micro MCU with external SDRAM.On the demo board, ST is using one series resistor termination for the bidirectional data lines. ST places this resistor at about 30/70% split of line length, where the resistor is 30 % of ...
Hi. I have a problem with ADC on a custom board with STM32L431CBY with external 24 MHz clock. Everything (UART, SPI, DAC e.t.c.) works fine except ADC. Clock initialization:static void setSystemClock(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_...
Want to know the compiler for STM3240G-Eval Board.
Hi,I am using one I2C based peripherals with Interrupt enabled.While using "HAL_I2C_Master_Transmit" and "HAL_I2C_Master_Receive", it seems to work properly with ISR.But, when I am using the following I2C_DMA:HAL_I2C_Master_Receive_DMA(&hi2c4, MPU_DE...
