Re: chibios + elua

chradev, hi yes makefile tested under linux only, i don't use windows, sorry Probably Lua installed in the host is needed as well. yes, elua build system based on lua, you may refer to elua documentation, how to build image under windows. the romfiles.h is generated by elua after following commands ...

chibios + elua

Hi!
just want to share example how to use chibios with elua.
Example for STM32F4 discovery
https://github.com/linvinus/chibios_with_elua

example lua

Code: Select all

Re: stm32F1x serial_usb circular buffer

Hi, That kind of mixing platform-specific code and generic code may work but it is not acceptable from an architectural point of view. i know, it was just for example. =) i'm also post example of low level function which should exist to make this code platform-independent. Anyway it is an interesti...

Re: stm32F1x serial_usb circular buffer

Giovanni, hi! I modify original function, so now it accepts data when enough space available in buffer, even if some process already begun reading data from buffer, may be it is good compromise between packet and transaction mode. Take a look. serial_usb.c: void sduDataReceived(USBDriver *usbp, usbe...

Re: stm32F1x serial_usb circular buffer

Now another question :) why queue callback don't have possibility to pass addition parameters? If it will have that, then you will not need for dirty trick with passing sdup through iqueue.q_wrptr? For example typedef void (*qnotify_t)(GenericQueue *qp,void* data); I'm don't understand for what use...

Re: USB enable connection API

Hello, Thanks a lot for USB driver. This is a feedback from a user. I think that it would be better to provide a API to enable USB connection. In STM32 example, there is a line like: palClearPad(GPIOC, GPIOC_USB_DISC); but, in case of my board (STBee Mini), it's GPIOA which controls USB line. Some ...

Re: stm32F1x serial_usb circular buffer

For some reason the USB callback is called twice and the application tries to reinitialize the endpoints, I will look into this.

no,
i'm check, it happens on startup, when usbInitEndpointI called first time.
second time it happens if reconnect usb cable.

Re: stm32F1x serial_usb circular buffer

ok, thanks for help! i didn't understand did you read about Assert in CDC example? It happens when debugging options enabled. It enabled by default, so by default CDC example don't work. by the way CDC example hangs on chDbgAssert(usbp->epc[ep] != NULL, "usbEnableEndpointI(), #2", "al...
