Re: problems with St7032i 2x16 LCD (IIC)

aahh, you were right guys. :oops: It is a reset issue. I found out that the Pin 8 XRESET was in fact floating instead of being pulled on VDD (as expected by me). next thing I found is that there is already a track to a MCU-Pin PD7, that I didn't found before when "reverse engineering" this board... ...

Re: problems with St7032i 2x16 LCD (IIC)

The uC likely should control the reset pin on the display thanks a lot Ray, I should have mentioned that this is a "given desing": my "board" contains the MCU and the LCD on one single PCB and I can not (want not) make any HW changes to it. So the external reset can or should not be used... (so the...

[SOLVED] problems with St7032i 2x16 LCD (IIC)

(please move into the right forum category if wrong here) I have to use a 2x16 LCD COG (Chip On Glass) Display with ST7032i IIC driver chip.

Re: [STM32F1] the best way to use 16MHz crystal (given board) ?

yes, this works as well (but without space between '|' and '=' (was a typo in your post above)),
I edited my post above accordingly ... 8-)

Re: [STM32F1] the best way to use 16MHz crystal (given board) ?

Pito, I checked that and it works :D [edit] there's only one additional line needed, so the final solution is (in "..\STM32F1\variants\YOUR_BOARD\wirish\boards.cpp" ): // Configure AHBx, APBx, etc. prescalers and the main PLL. wirish::priv::board_setup_clock_prescalers(); rcc_configure_pll(&wirish::...

Re: Review: CZ mini STM32F103VET6 (infos, documents, BL…)

when I first saw this thread some weeks ago, I was excited about this board, cause it seems to be versatile and it seemed to meet my requirements for a daily development device for testing purposes and so on... I ordered it on aliexpress (9€) but what finally I got yesterday looks a little different...

Re: [solved] Bootloader for a mini-PLC with STM32F103VE w/ 16MHz crystal

my crystal frequency is 16MHz do I have to add another (different) PLL setup sequence then in "hardware.c" ? would it be OK to write it like this (for 16MHz HSE) ? /* Configure PLL */ #if defined XTAL16M // 16 MHz crystal (using the Bit 17 PLLXTPRE=1 => HSE clock divided by 2 before PLL entry) SET_...
