The TSC of the STM32F051K4 works fine for all channels except for channel 1 of group 2 (G2_IO1). It does work but gives values much lower than all other channels. Also the delta (when your finger is on the touchpad is way lower than for other channel...

I'm using ST Visual develop and Cosmic to program a STM8S003K3 and I'm thought it would be nice to use the STM8 Standard Library (downloaded from ST.COM). Within a very short time I got errors telling me that I tried to put more code in the MCU than ...

Using STM32IDE LowLayer and STM32F051C8This code does not set the triggersource for the DACDAC_InitStruct.TriggerSource = LL_DAC_TRIG_EXT_TIM15_TRGO; DAC_InitStruct.OutputBuffer = LL_DAC_OUTPUT_BUFFER_ENABLE; LL_DAC_Init(DAC, LL_DAC_CHANNEL_1, &DAC_I...

In AN4566 the maximum sampling rate of the DAC of a STM32F407 is claimed to be 10.5 Msps but I'm not able to get any faster than 7 Msps before it starts to skip samples.The clock of the STM32F407 is set to 168 MHz.TIM8 triggers the DAC via TRGO.DAC1 ...

Posted on May 28, 2018 at 17:39Inputs for (at least) Timers and U(s)arts are being configured as PushPull outputs. There is no option to change this, so it produces the code below. I'm using a STM32F407VET and all the lastest STM32CubeMX software. (...

Now, that Application Note (AN5105) I had read. And AN4299, AN4310, AN4312 and AN4316. Reading UM1606 now =)BTW. AN4299 does mention that not all sensors will have the same sensitivity but I didn't think that they meant the port, but the combination ...

That's it. I have it connected to PA4 (G2_IO1). And the description of reduced sensitivity is exactly what I see. But I do not see a reduced sensitivity on PA5 (G2_IO2).As you mentioned to Imen, there is no mention of it in the DS, RM or Errata. But ...

The code you showed is the initialization of the ports. I used the same code on a STM8S103K3 running at 16 MHz and I got a delay of 500ns. We are talking about the initialization ONLY, right? Because I do not understand what you mean with "pass throu...

Are you by any chance measuring that delayed signal on an input port? If so what happens when you add an external pull-up resistor of 1 k to it? I'm guessing that the (high) resistance of the internal pull-up resistor and the capacitance on the pin (...

To get the baudrate of 625000 you say you need a MCLK of 16 x 625000 = 10 MHz. As far as I see STM8AF will go up to 24 MHz, so that means you have about 2 x 8 = 16 MCLK cycles to get a byte into the uart.

Re: Hello, i am using STM8L151C8T6 for learning purpose where i want to access the port of the MCU. I have initialize the port B and Port E of the controller high with the power on. (PB.0 and PE.0) and configure them with pull-up and in fast mode.
