Re: Custom PCB with stm32

The gerbers can be a bit tricky to find on the ST site which can be a bit overwhelming. try searching for something like: en.nucleo_144pins_gerber.zip which contains the folder "MB1137 Rev B" for the smaller chip use en.nucleo_64pins_gerber.zip MB1136-Rev.C I have also clipped sections fro...

Re: Custom PCB with stm32

Yes you can. I have made custom boards. ST provides gerbers for discovery and Nucleo, I used these as a starting basis with Ki-Cad. I think there are some Ki-Cad *-pill layout projects as well. I downloaded some, but never made them. I use an a ST link to program my boards. I keep meaning to write a...

Re: Nucleo-64 L476RG + ILI9486 4" Waveshare touch display, any libs?

I have some HX8357B displays sold by earthLCD as TDT320. These use a 9 bit serial protocol as some of the IMO configuration signals are not on the FPC cable. I also have a bunch of adafruit and Radio shack ILI9486 displays. When working with these displays, I find that it works best to separate them...

Possibly OT missing bootloader stm32cubeide code example

Greetings all; It has been a while since I posted here. I tend to program these days directly in cpp using the STM32 toolchain. (I do use the aurduino libs for some parts of the code.) Probably this could be posted to the stm forums, but as a charter member here, I tend to keep a tab open to this fo...

Re: STM32F103ZET6 Board hack

I swapped out an STM32F429 for a pin equivelent STM32F103 on one of the discovery modules (and all of my prototypes.) Stripped a bunch of the peripherals off the discovery. The whole reason was to get more memory. The cube tool has a good product selector section to see what footprint is. STM provid...

Re: Ethernet bridge for old Kodak SCSI scanner

The pi is a target device (Typically a hard drive emulation.) I am looking for the other direction host initiator. The pi also requires level shifters. I already have this on the existing STM board. The small Nikon scanner is what put Kodak out of buisness. Seems strange that back in the mid 1990s f...

Ethernet bridge for old Kodak SCSI scanner

I recently acquired an old Kodak pcd film scanner 2000. This is a suitcase sized behemoth that was state of the art back in 1995. I worked with the resulting scans when at apple back then. Part of one of the biggest and most unpopular products in history. The Kodak PhotoCD. When I was not at Apple I...

Re: STM32E407 Serial port 9 bits

I had a similar issue. In doing some research, there is no real difference between 8 bits with the 9th bit 0 and 9 bits with the 9th bit 0. This is what the start bits are for in Async transmission. They tell the system when to start clocking bits. Then come the parity bits. The stop bit is basicall...

Re: Mac OS X 10.15.2 catalina, cube MX and sw4stm32

This is a pretty old thread. I installed the Stm32CubeIDE recently and it works much better. I never did figure out why I can not open .ioc projects in MX apart from the most recent one. Opening the same .ioc project in cubeIDE it loads direct. Same for generating the .ld file under CubeMX. I no lon...
