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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on July 26, 2013 at 05:16I have a motor with a quadrature encoder and I want to get the relative (absolute after counting from home position) position. I tried getting the encoder count using an interrupt from one channel of the encoder and c...
Posted on June 04, 2016 at 05:32Hi everybody,I got a problem to implement USB CDC to STM32F407IG. Although looking into all the post here, still not solve my problem.I am using self-made board with STM32F407IGT6, The sch is simply connect as MCU US...
Posted on June 23, 2016 at 21:54I want to measure how long a signal is high as accurately as possible (preferably down to the microsecond). I started by triggering an EXTI interrupt one both the rising and falling edge of the signal. The EXTI handle...
Posted on June 23, 2016 at 20:11 I am working on getting familiar with the STM32F411 using ST evaluation board STM32F411E-DISCOVERY. I have written the following code using Eclipse + Ac6 STM32 + gcc (arm-none-eabi5.3 2016q1) I am a...
Posted on June 23, 2016 at 17:03I am a little confused with this call back function HAL_CAN_RxCpltCallback(). The end users are supposed to implement this function but there is already one in the file: stm32f0xx_hal_can.c. STM recommends do not mo...
Posted on June 22, 2016 at 14:40Hi all,I have a custom board based-on stm32F746G-DISCOVERY. I connect my board to ST-LinkV2 over SWD. I can dectect stm32f7 chip, but I can't flash it to 0x08000000 address. ST-Link Utility report :19:22:39 : ST-LINK ...
Posted on June 22, 2016 at 14:34I found this with the latest HAL come with the cubemx 15.1STM32F1 1.4.0UART_DMATransmitCplt never call HAL_UART_TxCpltCallback, it also did not change theuart->State cause the following uart transmit return with error...
Posted on June 23, 2016 at 16:01 I am trying to configure the DMA2 using the registers and I cannot get the DMA to work. I must be having a bad day because nothing seems to be working correctly. Here is my simple code that does not...
Posted on June 17, 2016 at 14:03 I've been trying to get this beast to wake up from stop mode when it received data on UART1. This is my approach in code int main() { SystemCoreClockUpdate(); initStopMode(); initUart(); //Init othe...
