I'm using the BlueNRG-LP and want to enable "Readout Protection". From the reference manual RM0479 it can be enabled by writing the UserKey 0xAAAAAAAA to DATA0/1. In the RF-Flasher 4.3.5 Openocd readout_protection.cfg file writes the UserKey 0xFCBCEC...
Hello,STM8S208RB.How can you read the AF bit in the I2C_SR2 register?When I try to read this bit, it is always 0 even if this bit is set to 1 (In debug mode I look at this bit that it is set to 1). For example, the following condition always gives th...
I have an 8pin IC marked 351 but I do not seem to understand what ST component it is. See the image. I will appreciate any help for identification.
Hello everyone.I am in trouble with the datasheet of STM8AF5288.There are only brief descriptions about TMU in the datasheet.What is the difference between TMU and ROP?How to use TMU?I can't find any documentation.Does anyone have more detailed infor...
Hi Team, Currently we are using M24C02-WMN6TP and is in NRND status. Could you please suggest an replacement which is FFF and active in status
What is the lower limit of the POR threshold value for the M24C02-RMN6TPT?The datasheet states "lower than the minimum VCC", but we need to know the specific value.With our hardware, the VCC only goes down to 1.0 V, not 0V. Therefore, I am inquiring...
Hello, where can i find the altium files for steval-1sa170v1?
Hi Everyone,I am measuring an Ac voltage which is biased on 2.5v dc on stm8s003f3. The input is coming from an op-amp. My problem is I am not getting a stable ADC value. there is always 2 3 point ADC fluctuation which ultimately fluctuates the AC vol...
Hello,Tell me how to pin windows such as Local Variables, Peripheral Registers, Memory in debugging mode in STVD? (When you enter debug mode, you need to open these windows manually; the next time you enter debug mode, these windows disappear and you...
Hi to all!I am trying to generate an analog signal using a DAC that is built into the MCP2221 controller. The problem is how do I control the output current? Maybe there are some schemes or built-in capabilities in the MCP2221 controller? Is it enoug...
