Hello all, I am working on a project with the 2.15 inch e-paper display from waveshare: [here](https://www.waveshare.com/2.15inch-e-paper-hat-plus-b.htm?sku=28916) I have tried this on a 3.3V pro mini and an arduino uno and the [example sketch](https://www.waveshare.com/wiki/2.15inch_e-Paper_HAT+_(B)_Manual#Arduino) does not work for me. It verifies and uploads with no errors but it just doesnt show anything on the screen. I wired my screen as suggested in the table on the waveshare website: ![image](https://europe1.discourse-cdn.com/arduino/original/4X/a/b/1/ab1a9bdcab47592436f00949d90639f94e530dc5.png) I have checked GxEPD but I can not seem to find the 2.15 inch on the [github](https://github.com/ZinggJM/GxEPD2) or when I try the example from the library. Though that is also giving me error about 'display' not being declared. I would greatly appreciate any help. ---

The arduino pro mini looks similar to this: ![image](https://europe1.discourse-cdn.com/arduino/original/4X/5/5/b/55be7334c96c02d8b93aebaa0ec30e4eda48e81e.png) The arduino uno is: ![8e3a980f0f964cc539b4cbbba2654bb660db6f52_arduino-uno-pinout-diagram](https://europe1.discourse-cdn.com/arduino/original/4X/4/c/4/4c43360f3746c854c53bce738259b98ffb1deb66.jpeg) ---

I only said similar because the one I got it from has a [different reset button](https://www.amazon.com/HiLetgo-ATmega328P-Oscillator-Compatible-ATmega128/dp/B07RS911JD?crid=354K91EYN32YC&dib=eyJ2IjoiMSJ9.dTxuef9aWfEgG0HnrhxL0_xxEWlKWqbUvMeSMd-hB27CMcQANgy2h-gF-kS7LT4dLEwnqaUfAZ44CodSlLfLfiKpxhZNpKIaXnSMmOtz3_fClyjojNlkx-NomePXpsbhstiBQP3HXJg3YE5JSxV2na17zOArPBUnnQJc4wM5FB1swezWazgmiQ48OpqhVq3tjKqFipOp_Av6cf7BT7C8TKJ7jKAHpnJf_qKWmwmkGGA.lEyo7PkvOpcTcvRv-eROKM9dJLeabYnLeSFb35zpJIQ&dib_tag=se&keywords=arduino+pro+mini&qid=1748814203&sprefix=arduino+pro+mini%2Caps%2C292&sr=8-2), its the same microcontroller: ![image](https://europe1.discourse-cdn.com/arduino/original/4X/9/2/f/92ffc57acd71d330a73e86baa6be99efad11e6e0.jpeg) As for power, I am using a [ftdi breakout](https://www.amazon.com/WWZMDiB-FT232RL-Converter-Adapter-Breakout/dp/B0BJKCSZZW?crid=31U7C6C5QZ6JP&dib=eyJ2IjoiMSJ9.d5vsloOHRmReaSnQwctqPwaCwp1Wa3n0GVCprQoSFRYq6wLspZZLZh2pIp240rjqMeEi92N7EUFl-GBtpNqMyQLcFB6iEyxiVFX95NSsm2ysSYpymK1YX7mq6Tl-XRPv7HE3HU3CfxSI-BZW8wvJ8FzMCV0E7LYPuk8wvTX1SnO4xqg6r9W_rOkcfrnR-ZHBOqD8iXE1QrFzrKKa3gp-anaQomMlOk3nctKHEowj3u0.L6dbD8kEBObmcHASEofKbDQXle610a68bVW-yFJtQ7s&dib_tag=se&keywords=ftdi+usb+to+serial&qid=1748814372&sprefix=ftdi%2Caps%2C205&sr=8-5) for right now ---

That link sez > Open the demo: 2in15\_e-Paper\_B\Arduino\_R4\Arduino\_R4.ino which looks like the code is for the Arduino R4, which is different enough that it may be necessary to use it for that code. a7 ---

I connected it like this: ![image](https://europe1.discourse-cdn.com/arduino/original/4X/a/8/2/a82e4e56f7f278e396fc80a3074aca9c444dbe78.jpeg) the issue isnt my ftdi connection because I have programmed the arduino and they work, I have gotten sensor readings from BME280 ---
