STM32F76 RMII Errata: Any hack/workaround

Posted on October 20, 2016 at 11:05Despite several promises to keep us informed about the findings around the error with RMII in F76, only ''ask your FAE'' was posted here. Now silently Rev. 3 of the F76 errata appeared, stating ''No workaround''. D...

Long wait for UART_FLAG_TC after DMA transfer

Posted on October 25, 2016 at 10:51Hello,While implementing a full duplex uart (115kBaud) communication on an STM32F303, I'm struggling quite a bit.My current problem is that the DMA1_Channel2_IRQn takes 170μs. I'm using DMA to TX data from the STM....

Can't produce 20 ms PWM for servo

Posted on October 25, 2016 at 15:54Hi. I am quite new to STM32. I would like to produce 20ms square PWM with adjustable duty cycle for controlling 2 servo position. MCU = stm32f103ret6 Using GNU ARM toolchain on Eclipse cdt. Use Timer5 Ch1,2 (PA0, ...

STM32F3 / HRTIM1 with Fault Interrupt

Posted on October 26, 2016 at 10:05Hello, I'm using the HRTIM1 to control a flyback converter.The FAULT5 input is used to stop the converter in case of an error. Now I want to use an interrupt service routine to react to the fault immediately. Ther...

STM32F334 HRTIM in push pull mode with 217ps resolution

Posted on July 06, 2016 at 19:27 Hello. I am working on project where i need to make 100-500W power supply from 12 to +-24V. I decided to use STM32F334 since it has PWM resolution of 217ps. I tested this, and it looks like it working...

Can't update HRTIM Compare Reg using HAL when running

Posted on October 18, 2016 at 05:46Hi, I'm trying to use the HRTIM for a high resolution simple PWM signal, using HAL. If I set the pulse length in the HRTIM initialise routine, then call SimplePWMStart() then I get the correct PWM output. Howeve...
