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...
I am not sure how to handle DMA channel from memory to peripheral. I have a circular buffer of 2*24 words that I want to load to PWM. I want to update(generate) new values once half and top of the buffer is reached. I was using similar thing for ADC ...
I am using the STM32f4-Discovery board, with the stm32f407vgt6 mcu. I am using it's USART peripherals at pins PB10 and PB11. Upon connecting another device to the USART communication something in the MCU failed, and now the board is not working prope...
Hello,I'm working with UART Communication between a RPi and an STMG070RB. For the UART communication I'm using the library function HAL_UART_Receive_DMA.I have an initialize in which the Receive function waits for 3 bytes to be received (My messagehe...
RM0316The reserved space is clearly indicated at the top, and the style changes abruptly on the next page, and the reserve is no longer specified. what is the result of missing addresses ? why can't a single style be maintained ? for clarity.
My Board is the STM32-G431KB Nucleo-32. I have a Mavlink Serial Tx/Rx (From a PX4 Autopilot) connected to PA10/PA9.I am attempting to receive serial data at 115200 8N1 on UART1 and then send it at the same rate on UART2. I am just doing a basic polli...
This is a suggestion, not a question...There's no support for dual buffer DMA mode in the ADC HAL, and it would be very easily added.Already did my own copying the existing function for the multimodeDMA.The problem is that CubeMX will wipe the code a...
I am using a current sense amplifier (INA190) to measure current. The output of the current sense amplifier will go to the input of the ADC on the STM32. The output range will (ideally) be between (0-VREF). From working with an external 16 bit ADC, I...
I built a project for the STM32L053 based on the BLE2_Application SensorDemoBLESensor.If I increase the length of the DeviceName (SENSOR_DEMO_NAME in sensor.h) beyond 7 characters, the call to aci_gatt_update_char_value() in app_bluenrg_2.c to set de...
Hello everyone, I've an STM32F7 Discovery Board. I've been playing with all of the peripherals such a USART, I2C, GPIO, LTDC and SDRAM. And, I've been problems with this last one. I want to do enphasis in that I use to program the device with Atollic...
I want to calculate the actual time the CPU spends in STOP2 mode.I wake up the MCU either by RTC Alert or LPUART.The issue is more relevant to LPUART wake use case, because it could happen before the RTC alert expires.I'm using RTC with LSI which con...
