STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello Team,I debug STM32F405 on my custom PCB using nucleo board and STLink utility software.Now, I have added a digital isolator on my PCB , and the STM32F405 MCU is powered by the isolated 3.3v supply & ground of the isolator.Now, the Nucleo boar...
All these functions have one problem, let's say in this function HAL_UART_Receive_IT(&huart4, data,5);the third parameter is the number of transmitted characters.If you enter more or less characters in the COM port of the terminal than specified in t...
Hi I try to send a message to the CAN interface, use HAl functionHAL_CAN_AddTxMessage.But the message not send.I verify with debug that the interface is allwais in Listering HAL_CAN_STATE_LISTENING.Do you have idea what is wrong?uint8_t CAN_TX(int16_...
I found this problem with STM32L476 but I suspect it may be a general STM32 quirk.The manual does not list the minimum and maximum value of UART BRR register. While the minimum value of 0x10 seems to be quite obvious, the maximum correct value in the...
Hello everyone, I’m currently trying to use an stm32l4r9i discovery along with a b-cams-omv. I saw that this camera is listed as a supported product for this board, however, I cannot find an example project of these working together. If anyone knows ...
Hi, I am using STM32H725 with the FMC interface and trying to clarify some issues.The initial issue was seeing extra writes/reads on the bus - this seemed to be fixed by switching the banks to use the 0xC...0 address range or configuring the original...
Hi there,I've been having difficulty trying to make the DAC channel 1 output 3.3v. The largest voltage that the DAC outputs is 2.56 volts which I measured with an oscilloscope. I try to set the output voltage to be higher with the following code snip...
Hello, I am interfacing audio Codec SGTL5000 with STM32H7 Nucleo board. I2S peripheral is initialized using the HAL init function. I converted a wav file to a C array and trying to transmit that to the Codec. STM32 is configured as Master TX and Code...
Hello ST community,I'm encountering an issue with my STM32 MCU where I observe higher than expected current consumption in stop mode when the SPI2 port is activated, and interestingly, the current consumption decreases when I deinitialize the MOSI pi...
Hello, I have an issue with the ADC conversion timing while using the DMA controller.I have only configured 1 ADC channel, 12b res. and the ADC clock is at 24MHz (50% of SYSCLK), and it shows correct conversion results (verified by a simple voltage d...
