Posted on October 13, 2016 at 17:56Hello,I am writing my own context switcher for tasking on the STM32F767ZI. This is a Cortex-M7. In the arm Generic user guide in the FPU section, it talks about allowing the processor to set Control.FPCA bit if I s...
Posted on October 13, 2016 at 17:02Hi, I�m using the STM32F4 Discovery TIMER3 with channel 1 and channel 3 in mode pwm output. I realised that when I�m use the module timer, I get ringing noise in the rising edge and falling edge of the PWM, and al...
Posted on October 14, 2016 at 20:04 I'd like to report a bug in the CMSIS I2C driver. The issue is in the file ''ARM\PACK\Keil\STM32F4xx_DFP\2.0\CMSIS\DriverI2C_STM32F4xx.c'' in the function ''I2C_ER_IRQHandler''. Description: The ...
Posted on October 13, 2016 at 10:30Hi, I would like to read pwm output from as5048 encoder and I dont know how to do it. I understand this pwm frame, but how I may read output pwm step by step? http://ams.com/eng/content/download/438523/1341157/1430...
Posted on October 14, 2016 at 15:17I'm building a bootloader and it shall run on a 100pin STM32F407 and a 64pin STM32F405. From reading the reference manual they seem very similar (except for some peripherals). My dev-environment does include an ass...
Posted on October 12, 2016 at 15:01Folks, I'm trying to get a VCP going on an F107. Is it correct that with USB on an F107 that the USB OTG interrupt should be going off every 600us or so? It seems unlikely, as that is a heck of overhead to put on ...

Posted on October 13, 2016 at 16:47Hello, why are ID Codes and ROM calibration values like TS_CAL1 not available in the device headers? This make writing portable code harder. Bye #id #calibration #device-headers
Posted on October 13, 2016 at 14:29Hi all,I'm going to design an ultra low power circuit which should work with battery for years, so i have to decrease the power consumption as much as possible, i'm using some peripheral chips like EEPROM(m24128), ...
