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 March 22, 2016 at 12:36DEAR ST: Participating in your forum, helping other people is ''enjoyable'' as long as the technology does not get in the way. So if I have something to say, I want to post it. What absolutely pisses me off is that I...
Posted on March 22, 2016 at 10:12 I have recently reversed-engineer some HAL source code and I see that sometimes a temporary variable is used to manipulate a register, for example uint32_t tmp = 0; tmp = hdma->Instance->CR; tmp |= hd...
Posted on March 21, 2016 at 10:56sdram clock run in 90MHz;LCD clock run in 24MHz.it not work(display ng).but LCD clock run in 18MHz,it work(display ok),but it looks blink,because reflesh rate low.huw to solve it?
Posted on March 17, 2016 at 23:09In the newer STM32 models, the I2C module allows to respond to multiple addresses in slave mode, through using a mask for own-address in the I2Cx_OAR2 register. However, if this is used, reserved addresses 0000xxx an...
Posted on March 19, 2016 at 12:14I'm working with CC2564MODNEM ( TI dual mode bluetooth controller). Tried to test their samples for STM32F4. I have described the problem at the link below.https://e2e.ti.com/support/wireless_connectivity/bluetooth_c...
Posted on March 21, 2016 at 17:01I am playing with STM32F030 device. Accordingly to ''DMA request mapping'' table (RM0091), it should be possible to use DMA1_Channel4 for TIM3_TRIG request, but I have some doubt how to do it in the right way.What ...
Posted on March 21, 2016 at 17:25We have a batch of boards in the field where the LSE crystal may be marginal and I'm wondering if there's a way to check for the LSE losing lock after initially being locked. That is, if on initial clock setup I get...

Posted on March 21, 2016 at 19:27I'm using an STM32F405/STM32F4xx family Mcu and attempting to setup Input Capture to measure Period and Duty Cycle of a PWM. After some trial and error after following section 13.3.6 PWM Input Mode I was able to get ...
Posted on March 19, 2016 at 13:21I am working with AVRs for almost last 3 years and decided to buy a stm32 nucleo boards to have some fun with ARM and bought STM32L476RG nucleo board.I started to write code in Keil MDK-5 with the help of Hal drivers...
