Posted on January 12, 2018 at 10:23I am using ♯STM32f070xB, In my program, I am trying to access registers (i.e. assembly code). My assembly code has branching instruction, which trying to branch to the function defined in another source file (.c).N...
Posted on January 16, 2018 at 11:43 I am developing IoT application on OpenWRT and USB. The STM32F103C8T6 is selected. After some research, I find its USB stack (CDC/ACM device) doesn't work well in some Linux disto. The same situation also appli...
Posted on December 06, 2017 at 22:11Hello,The title says it all. There's a a mysterious delay in USB_SetCurrentMode in F7 USB LL driver (stm32f7xx_ll_usb.c V1.2.2):Does any one know the origin/need of this delay? There's no comment (or time units) a...
Posted on January 14, 2018 at 16:15HiI am working with 'stm32l433ccu6' ARM processor and I got a serious problem which cause Hard Fault Error inside my firmware. The problem arise when I run PDM_Filter_64_LSB() function from libPDMFilter_CM4F_keil.l...
Posted on November 23, 2017 at 10:10I have a custom board based on STM32F412VE that communicates with the PC via the UART1 (pin PA9 and PA10 with 100K pullup). I have problems communicating with the bootloader. Here is an oscilloscope screenshot:As ...
Posted on January 15, 2018 at 06:17Hi,I am looking for an USB host example code for STM32F215VG using Standard peripheral drivers. I tried to modify the sample code provided along with SPL driver library but facing some issues.#usb-host #stm32f215
Posted on January 11, 2018 at 12:30I'm using stm32L476 mcu and I'm trying to configure and enable a set of timers in my stm32 project using cube, hence HAL libraries. Reading datasheet I found TIM2, TIM3, TIM4, TIM5, TIM15, TIM16, TIM6 and TIM7 coul...
Posted on January 11, 2018 at 20:33I have been having an issue in my project with LWIP. The network seems to run fine, the protocols all work, but then (usually a day or two later) the stack just stops running. It seems to happen when trying to make...
Posted on January 10, 2018 at 21:55My development hardware is the Olimex P107 board (Rev D: STM32F107VCT6 MCU, LAN8710 PHY).DHCP and ping in a bare lwIP example are working fine. Now I want to combine FreeRTOS and lwIP. I'm using the latest STM32Cub...
Posted on December 12, 2017 at 08:24It seems that the cubemx doesn't let us change CUSTOM_HID_EPIN_SIZE or CUSTOM_HID_EPOUT_SIZE, and in the codes, we don't have a user defined part for this. so this cause to define it asthe default value which is 0...
