How GPT Trigger ADC without using FSP?

Hi, I would like to trigger ADC conversion with GPT capture and compares events without using the FSP configuration. I couldn’t figure out how to do it, is there any example project about it? Thank you

    Hello, It’s easy. see the section, 3 of the manual (RA4M1) To trigger the A/D, write to register ELSR8 (R_ELC. ELSR (8), and the number you write to that register is the event number shown in table 18.3, nearly between 0x57 and 0x96, depending on which timer, which event (and maybe which processor).Read more

    Hello,

    It’s easy. see the section, 3 of the manual (RA4M1)

    To trigger the A/D, write to register ELSR8 (R_ELC. ELSR (8), and the number you write to that register is the event number shown in table 18.3, nearly between 0x57 and 0x96, depending on which timer, which event (and maybe which processor).

    First, you have to enable the ELC registers by writing 1 to R_ELC. ELCR and writing to the module stop register.

    You also have to inform the A/D by writing 9 to ADSTRGR (see section 35.2.12)

    Thank You

Hi,

We’re seeing a positive pulse in pin 6.5 while powering up, resetting & programming (via SWD). Please see the attached screenshots.

The pin is port 6, which also has SWD and reset lines. We tested the pin with various configurations via PSoC creator, but could not find out the root cause. Can anyone help us in correcting this issue?

Edit We’re also seeing such an issue in pin 11.1

    Hello,

    By default, all GPIO pins start out at reset as Analog_HiZ. This means the pin though configured at initialization as a draw-down thing inactive low launches life floating until the boot initialization is complete.

    still, also I suggest an average worth resistor( 100K?) drag-down to GND If this is your project case.

Hii,

We’re using the below-mentioned IC in our design. While trying to flash the same using J Link Debugger Plus from Segger, the GUI of the tool asks to select the microcontroller from the drop-down list.
But Under the OEM, Infineon, the CYT2B7 series isn’t displayed. Hence we’re unable to select the target device from the GUI. Without selecting the target device, unable to proceed further with the flashing.

Hence I kindly request you to help me in this regard at the earliest.

Hello,

I am in the process of learning my way around microcontrollers and designing an IOT device that will include a thumb keyboard. The font used will be an older one used on BBS systems and I envision holding control keys to utilize the upper area of the fonts for drawing.
As similar, I am aware that the esp32 lacks the pins demanded to program a keyboard so I am thinking a keyboard controller chip would be needed. Does anyone have a recommendation on what I should use?

I looked up many but they feel to be more fit for a laptop and apparently preprogrammed.

Thanks & Regards
