Why is my uart rx not working?

Code shown in details. I am guessing something is wrong with clocks - this doesn't make sense though since tx is working just fine. I see signals just fine on the scope. Both tx and rx are high during no transmit. Clocks and initialization code shown...

Resolved! how can i compute flash crc for STM8AF5288 MCU with STVD IDE & Cosmic compiler ?

can i use the _classb_checksum160 function on STM8AF5288 MCU for flash integrity check at startup ?

i had received this function from the ST Micro self test evaluation package for MCU STM8S207RB

Resolved! Hi experts! Do you know what is my issue? and how can I solve it? I'm using the ST-link v2 with the STM8 part as you can see below.

Hi support team, I'm working with the stm8a-discovery evaluation board and ST recommends use cosmic c to used with ST Visual Develop software.. Could you please bring me the software please? Best regards, Tania

Resolved! Is the new STLINK-V3 compatible with STM8?

ST Visual Develop

Hello, everyone,I have a problem with ST Visual Develop, version 4.3.12 (See attachment 1)If I launch ST Visual Develop as administrator, I am not allowed to enter debug mode, but I get the message: "** Connection error (usb://usb): gdi-error [40201]...

Resolved! Hi,I am working on STM8s0003f3.I need to read analog voltage from ADC_Channel_5 I have stuck at how to initialise channel cmd for the same as I dont find any ADC_Read examples.Can someone help me sort it out please

STM8L151K6:COMP2...Does closing WINDWE analog switch (for Window mode) disconnect COMP1 non-inverting input from AS14 in the analog switch matrix?

Using the Cosmic IDE, I have the non-inverting input of COMP1 driven from PA4 by closing RI_AnalogSwitch_14 and RI_AnalogSwitch_0 and enabling RI_IOSwitch_3. I have COMP1 configured for COMP_Edge_Rising and the COMP1 interrupt is enabled. I see inter...

Able to control STM8S nucleo board, but same code to chipset on my own board does nothing. How can I debug?

I use STVD with the cosmic compiler, SPL library and STVD to flash. I am able to control the STM8S208RB Nucelo board with this setup, and verify the board is functioning correctly.I then lay out a PCB with a STM8S003F in a TSSOP-20 package. The layou...
