Re: Success really isn’t optional

Welcome to Ultibo. Pascal's new frontier. I never really used Zero's till Ultibo USBboot got working. Still mostly for coding practice but that's further than I got with Linux on them ;) Not perfect for realtime (ARM A series restricted) but much better than Linux. I had trouble with i2c sensors use...

Re: Roll Call

Still here, but been busy with other stuff, like using Ultibo instead of learning Ultibo ;)
OpenGLES yikes, trying to get my head around the language and concepts.

Re: Arm Embedded

our interest is in using the full power of a microprocessor instead, without the limitations of an OS. Understood ;) For me doing a RTL for a smaller micro is a tiny step to figuring out how Ultibo works. Plus using the same toolset is a bonus. Eventually full Ultibo could go down to CortexM4/7 and...

Re: ILI9340

It seems to also have the DPI interface, but than uses more pins on the Pi's.
I think framebuffer support for that exists? at least in Raspbian via the GPU?

Re: ILI9340

There is a link on the Pi forums to someone who wrote a driver that only updates the changed pixels. SPI TFT's are limited to SPI speeds which means usually <20 fps. I have yet to get one and try but using the SMI/parallel data 8080 mode should be faster. The chip itself has 8,9,16,18bit 8080 interf...

Arm Embedded

Been some discussion of using PIC's and Propellers. Known about Free Pascal Embedded target for a while. http://wiki.freepascal.org/TARGET_Embedded#Build So I did ./ppcrossarm -i > armmicro.txt Now I have a file with the supported micros the Ultibo cross compiler does. I can go through the list and ...

Re: Propeller CPU connected to Ultibo/pi

Was looking for some MQTT free pascal source and found this.

Zicog has some Pi to propeller loader code, in C but maybe of some use to those that can figure it out ;)

Re: PIC Peripheral Interface Controller connected to Ultibo

LPC1114FN28 but none of my suppliers have the DIP version in stock :( Is the DIP era over? Will the Prop1 be the last Micro in a 40pin DIP? i would prefer ARM chips because Ultibo could be used as the IDE/compiler. All that needs to be done is a cut down RTL and libs :o Picking a small one means a s...

Re: PIC Peripheral Interface Controller connected to Ultibo

I recently got two i2c and two SPI's working for a dual smart sensor interface. The SPI is for programming the Smart sensor's cortex M0 code into a SPI flash and the i2c is comms to the sensor. Never needed to do the SPI part because I managed to program the SPI flash in Raspbian with the flashrom p...

Re: NRF24l01+ Rf network driver library

What is the small circuit board in the upper right? That would be the NFR24L01 PCB module ;) https://www.amazon.com/Makerfire-Arduino-NRF24L01-Wireless-Transceiver/dp/B00O9O868G You really have to be crazy to make your own PCBs for these, it is just not worth the trouble. Most of the NRF24L01 PCBs ...
