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...
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....
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, ...
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...
Posted on October 26, 2016 at 14:43Hello, I discovered a bug in latest HAL library, it is described here: http://blog.gorski.pm/stm-hal-usb-library-hard-fault
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...
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...
Posted on October 26, 2016 at 11:40 Hi all, i use stm32f3 discovery and i develop a project with IAR but i have faced a problem in fixing my loop periode to be more clear : i use the accelerometer and the gyroscope of th stm32f3 discovery , ...
Posted on October 26, 2016 at 14:11I'd like to transfer data from STM32F446 MCU to an array of ST1642GW LED drivers efficiently. Right now, I do so by a soft SPI interface which is limited in speed and consumes too much CPU time. The real challeng...
Posted on October 24, 2016 at 09:56 I have just updated to Cube v4.0 which I also think updated the firmware package for the chip I am using (STM32F030RCTx). There is a bug in the initialisation code for the DMA that causes the project not to be...
