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...
Posted on March 07, 2015 at 00:35Is there a good way to implement a UART driver that uses DMA and freeRTOS? Or should I let the RXE TXNE interrupts handle the queueing and use no DMA?It would be nice to use tha DMA to shuffle data to an array and th...
Posted on March 16, 2015 at 15:53Hi, I need to modify a PWM inside an interrupt, I though that It would be easy, just changing CCR2 to the new desired value but it is not working properly.The change is not happening each pulse, it is a bit random.. ...
Posted on March 16, 2015 at 16:25 Working with the STM32F439 UART and originally used DMA for TX and RX, and that was working. For other reasons I wanted to change RX to use interrupt, and I had difficulty getting it to work... I got things work...
Posted on March 16, 2015 at 12:36Dear users, I recently got a present - STM324x9I-EVAL board. So far I've been tinkering with Arduino's and made some mini projects. But this one surprised me - I saw almost no references and ''how-to'' online (in com...
Posted on March 16, 2015 at 08:52 I am trying to implement this project using the demo files provided by ST ''STM32Cube_FW_F0_V1.0.0\Middlewares\Third_Party\FatFs''. I have also written the necessory code for low level SPI driver. The command...
Posted on March 16, 2015 at 03:39Hi,I'm using my STM32F4DISCOVERY board with the STM32F4-BB shield which contain an Ethernet PHY/connector.i found many example for Ethernet communication using lwip and they work fine.i want to use my STM32F4 board a...
Posted on July 17, 2013 at 11:42Hey I'm running the STM32L1 chip with an XBEE unit and everything works perfectly except my Tx adds bits when there is an even number in the unsigned char (I typedef this as BYTE) being sent. Shows in Putty and X-CTU....
Posted on February 27, 2015 at 03:04Hi there,I have the STM32F3 discovery board and running a FreeRTOS.I also have the USB virtual Com port (VCP) code from here: http://www.pezzino.ch/stm32f3-discovery-usb-virtual-com-port/ I have tested the USB VCP...
Posted on March 16, 2015 at 08:12I use UART + DMA to receive unknown length packet, and use IDLE interrupt to monitor the end of the packet. It can recevie IDLE interrupt, but in HAL_UART_IRQHandler I read SR register and IDLE flag is 0. I never en...
