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 February 04, 2017 at 13:06I am trying make communication between RN4020 Bluetooth module and STM32F411RCT MCU.They are connected with UART and CTS/RTS, hardware flow control is recommended for this communication.It would be great if I coul...
Posted on February 08, 2017 at 16:54Currently CubeMX supports only FreeRTOS v.7.It is a really old version without power save features. This year FreeRTOS v.9 is already available. Are they going to support new FreeRTOS versions? Why they didn't sup...

Posted on February 06, 2017 at 02:14CubeMX version 4.19 fails to load the I2S DMA configuration when used in RX mode (peripheral to memory).I have confirmed this issue is repeatable over a range of parts and I2S modes. The consistent factor seems to...
Posted on March 06, 2017 at 22:42There is an extra 'else' at the end of UART_DMATransmitCplt function which prevents the HAL_UART_TxCpltCallback to be called in normal (non-circular) mode[...]} /* DMA Circular mode */ else { HAL_UART_TxCpltCal...

Posted on April 06, 2014 at 17:27Hi, It is possible that the hardware has gone bad, but I consider it unlikely. I swear that this use to work. The same software works OK on the STM3221G-eval board. I know there is a signal at the CAN rx input to th...
Posted on March 02, 2017 at 14:52I've recently set about to use the Low Power Timer on an STM32L071. The idea is to set it to count up to a particular value then stop, the code for which follows:void hal_Timers_LowPower_Once(uint32_t period){ LPT...
Posted on February 28, 2017 at 08:19Hello!I am encountering problem that the USB battery cannot power up the STM32 Nucleo F411RE after I enabled the UART communication with ESP8266 Nodemcu.I can have the PC USB working ok and see the UART communicat...
