I wrote a very basic slide show program in MicroPython for the Inky Frame so I could preload them with some images to make them a better gift. It just shows every (600x448) JPEG in the `/slides` directory on the SD card in a loop: [sdslideshow.py](https://github.com/kevinjwalters/micropython-examples/blob/master/pico-w/sdslideshow.py). ---

Thank you for sharing. I don’t own an inky, so I can’t try it. But I like when people share there code so thumbs up from me. =) ---

I wrote that quickly in late July just after my Inky Frames turned up. Pimoroni posted a more elaborate example while I was on holiday: [Pimoroni MicroPython Examples: Inky Frame: Image Gallery](https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/examples/inky_frame/image_gallery). ---

I needed a retry loop for mounting the SD card at power up. It’s fine afterwards but my code throws an `OSError` if I don’t have something like this in there. ```auto sd = None last_exception = None ### First one often fails at power up for _ in range(15): try: sd = sdcard.SDCard(sd_spi, Pin(22)) uos.mount(sd, SD_MOUNTPOINT) break except OSError as ex: last_exception = ex time.sleep(4) if sd is None: raise last_exception ``` Perhaps there’s a better way to achieve the same thing there? Oh, and I know I’m not necessarily handling `uos.mount` errors well. ---

I have a Pico RGB Keypad running Circuit Python. It’s set up as a USB HID device. It errors out waiting for my Windows PC to boot up. I ended up putting a time.sleep as my first statement in my while true loop. My code doesn’t run until the PC is booted up and waiting at the log in screen. I know the keypad is ready when all the pads light up a dim white. Long story made short, It’s not an elegant or sophisticated solution, but it works. ;) ---

I just updated the code. It now has: - sleep support on battery power with next image every 4 hours (possibly a bit less on my Inky Frame as my clock appears to run fast), - buttons for navigation and - an introduction/instructions screen currently implemented as a JPEG image (see below). ![introduction](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/7/75fb7a9a26db74ead8d3f04a9e3ce1727ef97427.jpeg) ---

This is cool! I tried to do this aswell, sadly I think the ram prevents me from running this with 3k images on the sdcard: Traceback (most recent call last): File “”, line 158, in MemoryError: memory allocation failed, allocating 8192 bytes at: files = list(filter(JPEG\_RE.search, uos.listdir(SLIDE\_DIR))) How many images do you have on the sd? ---

I’ve been giving them away as gifts with 10-50 images on, nowhere near 3000! It turns out there’s an `uos.ilistdir` function which is an `iterator` and that makes it possible to read the directory without loading large chunks of FAT32 directory content into memory. I’ve just re-coded my slide show to use that. I don’t have time at the moment to setup a test with a large number of images but you’re welcome to have a play with it. Same location on github, it’s `v1.6` in the code comments. ---

Glad it worked. The frame looks really nice. Does that have room for AA batteries or are you using something slimmer? ---

I wrote [Instructables: Battery-Powered Digital Picture Frame Using Pimoroni Inky Frame](https://www.instructables.com/Battery-Powered-Digital-Picture-Frame-Using-Pimoro/) for a bit more detail on using the slide show program including a bit of power profiling with Nordic Power Profiler Kit II. I mentioned @ingurum 3D-printed frame as it looks really good. I don’t have a printer to try it out myself. ---

Very good writeup! Judging from the PPK2-graph, the wlan-part of the pico is active. These spikes at 150mA suggest activity from the radio. Also, a normal pico needs something like 25mA while active, and the difference to 50mA is probably not due to the inky. So it would be interesting if there is a means of shutting down the radio or maybe even starting with a deactivated radio. The wlan-chip on the picow does have the necessary interfaces, but I’m not sure if they are exposed by MicroPython. ---

Great instructable kevin! I used a lipo and I am working on V2 for the case to include an amigo pro for charging. Also I’ll deepen the case for the included AA batteries. I am planning to improve the snapfit as well (maybe screws) ![20221209_095511](https://us1.discourse-cdn.com/flex016/uploads/pimoroni/original/2X/2/2877fd6a836bde8c3377cfba9003a70969da1550.jpeg) ---

I just checked the SD card and it was empty. Not sure how the directory got deleted,but that solved the loading problem. I am not getting any lights from buttons interaction. Is that normal ? The introduction.jpg must be on the root of sd card? SLIDE\_INTROFILE = SD\_MOUNTPOINT + “/introduction.jpg” ---

Yes, root directory for the introduction.jpg. There’s an image of layout in step 3 of [https://www.instructables.com/Battery-Powered-Digital-Picture-Frame-Using-Pimoro/](https://www.instructables.com/Battery-Powered-Digital-Picture-Frame-Using-Pimoro/) There’s no current use of LEDs but it’s on todo list. It would useful to indicate button presses as Inky Frame (using MicroPython?) requires an unusually long press to wake. ---
