Disable PWM at logic low
Posted on February 12, 2016 at 17:52At certain time instant I need to disable the PWM. The problem is that I don't want to disable when the logic is high, but low. How can I obtain this? Thanks.

Synchronize TIMx, SPI1 and SPI2
Posted on February 13, 2016 at 02:40I'd like to set up TIM1_CH1, TIM2_CH1, and TIM3_CH1 to be synchronous in the sense that the counters reset to 0 on the same clock tick. It seems like this is possible using ''HAL_TIMEx_MasterConfigSynchronization...
Pure ARM GCC toolchain
Posted on February 12, 2016 at 16:20Hi there,Is there any support for a pure ARM GCC toolchain for STM32 microcontrollers?I essentially mean this: linker scripts and startup code.I understand Atollic TrueSTUDIO provides a similar path to this, but I...
STM32F429i Disco Problem ADC+DMA Continuous Scan Mode
Posted on February 13, 2016 at 12:18Hello everybody, I've configured the STM32F429i-DISCO eval with CubeMX (vers. 4.12.0) to read ADC1 IN5 (pin PA5), IN13 (pin PC3) and Temp Sens channels in continuous scan mode with DMA enabled. Attach you can find...
RTC fine until I write to the counter
Posted on February 01, 2016 at 05:26I'm using an STM32F100RB. I've started with the reference code RTC/Calendar/main.c and it all works fine until I try to use the RTC_SetCounter function. All is OK when it gets called on startup with a value of 0...
STM32F4xx Using DMA Transfer Complete Callback with SPI
Posted on February 10, 2016 at 22:18I just posted this message but it seems to have gotten lost by the forum system. :( Anyway, I'm using SPI with DMA to talk to a SPI flash chip. I'm using the TXRX complete callback handler to detect when a transfe...
Configuring SDADC and ADC Repeat Triggering With DMA
Posted on January 16, 2016 at 07:06I am triggering ADC1 from TIM4->CCR4 and SDADC1 from TIM4->CCR1. ADC1 is configured for regular conversions and no injected conversions. SDADC1 is configured for injected conversions and no regular conversions. For...
STM32Cube Bug - HAL_RTCEx_SetWakeUpTimer_IT
Posted on February 12, 2016 at 22:42 I'm using the HAL libraries to set up and control the RTC features of an STM32F3 device. The RTC is based on LSE, and is running fine. However, when enabling the wakeup timer, no interrupt was ever generated ...
How to generate PWM output using timers on PB0 and PB1
Posted on January 21, 2016 at 15:58 Hi all, I have the stm32F429 micro and I need to generate 2 PWM Output (see below) using pin PB0 and PB1. I tried with toggle mode and TM3 on ch3 and 4, but the duty is 50/50 and is not good. There is a phase...
