Posted on August 09, 2017 at 02:36Regarding ADC resolution, 12 vs 16 vs 24 bit, is this software or hardware dependable? Looking at STM32F37x family, seems like they have an 'effective number of bits/ENOB' of 14 bits, using sigma delta ADC they adve...
Posted on August 09, 2017 at 20:05I am using stm32f429 discovery board. When I use pwm on any timer, I am not getting correct outputs, that is my duty cycle is not matching the values in the ccr and arr registers.void enable_gpio1(){ RCC ->AHB1ENR |...
Posted on August 07, 2017 at 20:59I am testing out the USB HID (otg fs) feature of my board with stm32f407vet6 mcu. I used stm32cubemx to configure it and i didn't add anything to the while loop in main c, just seeing if the device can be detected o...
Posted on August 08, 2017 at 19:47In my code for pwm on timer 2 in stm32F429, I have to use multiple channels (2 at a time). However only my channel 1 pin is giving pwm output. Please advise me what to dovoid enable_gpio1()//setting pin 5 of port a ...
Posted on August 03, 2017 at 23:47I am trying to import an example STemWin project to System workbench. I want to copy it, because I do not want to ruin the original one, I may need it for another project later, but if I check the copy alternative, ...
Posted on August 09, 2017 at 19:41Hi First I will give info about my project.I am generating PWM using timer, then SPI using Full Duplex slave mode and a GPIO pin. PWM is connected to SPI sclk and GPIO is connected to NSS.I am transferring data from...
