avrdude error: program enable: target does not answer (0x01) avrdude error: initialization failed, rc=-1 From the error message it looks to me like you have the driver installed correctly. The bit of the error message above is saying ‘I can’t talk to the device for some reason’. That could be for a...

Just to follow up on that post, we now have the RM95 LoRa module in stock: https://hobbycomponents.com/lora/1188-rm95-lora-868mhz-band-wireless-module The forum page can be found here... https://forum.hobbycomponents.com/viewtopic.php?f=74&t=3120&p=8792 ..and our Arduino library for the RM95 can be ...

Yep, that now works, thanks. On the Pro Mini with a test text screen of circa 64 characters the software SPI takes 1954mS to write the screen and in hardware SPI mode it takes 387mS. Excellent - thanks again for your help. I could eke out a bit more speed by directly writing to the ports for the co...

Thanks again. Your setup looks correct to me but I think I’ve found the problem… Just to be thorough, I connected it up in your configuration and with the hardware SPI version it started to do weird things. I think I’ve pinned it down to the wrong SPI mode. Must have been just a fluke that it worked...

If I comment in HCDisplay.Init(CE_PIN, DC_PIN, RST_PIN); put options.h to '#define ST7565_SPI' then I get a blank screen. Odd, I have tested it on an ATMega328 based board and it's working fine for me. Did you remember to move the DIN and SCK pins over to the hardware pins on your Pro Mini? DIN -> ...

I’ve just uploaded a new version of the library (V1.2.1) which hopefully fixes the compile errors for Arm devices. I’ve tested it with a generic ESP32 and it’s now working fine for me. I’ve also added a hardware SPI option (ST7565_SPI) so if you want to give it a try just uncomment the appropriate l...

Overall I am impressed with these displays, far betteer than the often used 0.96" and 1.3" OLEDs, and of course you can use them outdoors. Thanks for the feedback..... The HCDdisplay library does work with an Arduino such as a Pro Mini but not with a DUE or ESP32. Assuming you are seeing compile er...

I have new hardware with exactly the same problem. If neither programmers were purchased from us then I’m afraid I can’t give any advice on installing the version of driver/software we supply as it may not be suitable for your programmer(s). The best advice I can give is to contact the seller who y...

No luck, I'm afraid, following your instructions to the letter. I just get "unknown USB device" in the device listing, I am strongly suspecting that I have broken hardware. Try following these steps to confirm if your USB interface is working properly: 1) Open up device manager and find the entry f...

the software for programming is downloaded OK but the driver software for the PL2303 seems to be rather complex to get loaded and running. If Windows has automatically installed a driver, or you have installed one from a different source you’ll first need to completely remove it. You can do this by...
