Re: STM32L476RG

I'm a new user of Nucleo STM32l476RG. I'm wondering what the purposes of tools->DOSFS menu in arduino ide is. Can we use for this menu for data logging with SDIO mode? The STM32L4 core as a filesystem called DOSFS (which among other things allows stream writes, an a power safe mode). It does suppor...

Your best bet is to raise an issue on the L4 repo in GitHub.com/stm32duino
It's a bug in ST's core. Neither the STM32L476 nor the SAMD core have those issues (nor does Teensy).

Re: STM32L4 Core

Thanks will try to change the A/D setting. My DFU problem may can be that the bluepill hardware are diffrent. I did only get the ST Dfu dected by the computer so went to ST-link. Dont get usbserial to work but i think that is only computer problem as serial1 work over Fdi adaptern. It is some usb d...

Re: STM32L4 Core

I put a L433 on a bluePill and run it as Butterfly L433 and it works. Soo thanks for all work. Change the board.txt to upload with ST-link-V2 as hade to move the boot jumper to get DFU upload. Now I only the Port name ex PC13 to led are there any plan to have port name and pin name as we have on F1...

Re: STM32L4 Core

Can you elaborate on that? I would really like to work on the l476 platform, and I don't mind giving away, say, the LCD. What adjustments would be required to use the STM32L476GDiscovery? Thank you Interesting. What is hooked up wrong, and what solder bridge is needed ? Yes. That is my question The...

Re: STM32L4 Core

hey, i'm back after a while, wondering if the STM32L496 will be supported in the future sometime :P it has less uA/mhz power consumption (320k), more sram and more flash (up to 1mb) also, does anyone have an example on how to put the flash ic into XIP (or similar) mode, as the datasheet says it can...

Re: STM32L4 Core

It has USB hooked up, but USB_VBUS is hooked up the wrong way, so you have to mess with a solder brigde. Can you elaborate on that?

Re: STM32L476RG

Is there some kind of driver, or it's not implemented yet?
This should be one in the next few weeks for the STM32L4 core. Time-triggered ADC, which is what you seem to be after ?

Re: I2S example code

Victor, that took a while to get to that. Code has now been updated on github.com. I ended up using this code: size_t I2SClass::write(int32_t sample) { if (_state != I2S_STATE_TRANSMIT) { if (!((_state == I2S_STATE_READY) || (_state == I2S_STATE_TRANSMIT))) { return 0; } _state = I2S_STATE_TRANSMIT;...

Re: iwdg_init() and iwdg_feed()

Quick question. If LSI feeds IWDG, could IWDG be disabled by turning off LSI ? Do anybody try ?
