Posted on April 22, 2017 at 22:02I've been able to get a graphical image displayed on the LCD on the STM32F746NG-DISCO board, using only internal SRAM and the L8 pixel format using the CLUT, but it is only showing up as linear monochrome output, i.e...
Posted on April 23, 2017 at 21:42I have a STM32F429I-DISC1. When I power it on with a PC everything works fine but when I use a external power supply the board stays in reset mode. I updated STMCubeMX to the newest firmware STM32Cube FW_F4 V1.16.0 b...
Posted on December 26, 2015 at 20:50Hello,I'm quite new to the ARM development and hope that you can help me.I have a ILI9341 LCD without touch and wanted to display something :)I got the library for an STM32F4 from this site and tried to rewrite it...
Posted on April 23, 2017 at 18:02I started to debug the STM32 project using NUCLEO-F411RE boardAC6 System Workbench (win_64bits-v1.14.0)STM32Cube_FW_F4_V1.15.0 (example to Blink LED on board)STSW-LINK009 (V1.02) Checking the ST_Link Debug Proper...
Posted on April 22, 2017 at 08:12Do i need a pullup 1.5K resistor on D+ for USB Full Speed when the USB is configured as a Device (peripheral)? I recently build a custom circuit board without the 1.5K pullup and the PC didn't detect it? unfortunate...
Posted on April 20, 2017 at 18:01STM32F437This is an update from my previous thread:https://community.st.com/message/154808-stm32f4-adcdma-always-returns-same-value The ADC2 DR has the right value in it but the DMA is not working as I thought it wou...
Posted on April 23, 2017 at 09:44After using STM32CubeMX (4.20.1) to use LwIP 2.0 with UDP, TCP and HTTP successfully I try to use SNMP and enable SNMP. After code generation, compiling in SW4STM32 (1.13) fails with many attributes in some structure...
Posted on April 23, 2017 at 09:59Presently I am porting a project from the CooCox platform (lwip 1.4.1) to SW4STM32 platform (lwip 2.0). This portage is almost straightforward except for the porting of the SNMP agent.I do the portage on a STM32F4 bo...
Posted on April 21, 2017 at 00:02I am using the ov9655 camera for image processing with the STM32F4 microprocessor. I want to convert the camera format from RGB to YUV(grayscala) . How can ı do it ?/* OV9655 Camera size setup */ #if defined (QQVG...
Posted on April 22, 2017 at 16:17Hi, I am trying to use ADC with DMA on the STM32F407 in two channels (PA1 and PA2), so, basically I created the project using CubeMX, exported it to Coocox, ran the debug to fill the vector and imported these points...
