Update DIY: STM32F103C8T6 („BLUE PILL“) + ST Link V2

got yesterday my STM32F103C8T6 (earlier post)->diy-stm32f103c8t6-blue-pill-oled-tft-display/
1,55€ (inkl.shipping)->Aliexpress -> Link
first->its smaller than i expected (see 2.picture) and its very „friggling“..

i thought, no problem, i use my Pi, wire it up like in some Youtube-Videos, use the Arduino IDE and begin to upload a sketch etc..
but:Wasn´t“ ; )..got always a „STM32flash -> „Device init failed
(use btw. first my USB-serial adapter with RX,TX and ground->Arduino said:“Device not recognized“)..
googled through a thousand STM32-Arduino-forum/threads, millions of hours, and the final conclusion is:

Buy a ST-Link V2 !! -> 1,68€ Aliexpress -> Link

directly from the beginning (with a STM32F103C8T6)->strongly adviced/recommended from my side here too !! 😉
(hope this will do the trick !! (toi,toi,toi->german phrase)) 😉

New ES9038Q2M-forum link + other pictures (things)

here´s another, fresh, ES9038Q2M-forum-link: http://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board.html

by that i´ve found some further, interesting pictures concerning the „targeted“ DIY-DAC !! 😉

first, i´ve found another ES9038Q2M-chinese-board with a 15V (DC)-plug->

second here´s also again a little „picture“-description“ how to connect a „DSD„-Led to a XMOS-Usb-Bridge.. 😉

and third, heres a picture how to connect a bluetooth-receiver-modul (CSR-8670/8675) directly to an ES9028Q2M (in this case) via I2S..

SMSL M8A – ES9028Q2M DSD512/768khz capable..

according to their marketing, the M8A with one ES9028Q2M and a XMOS XU208 inside, is, as per their description, absolute DSD512/768khz-capable:
they say its primarily „solved“ by their custom-made/specialized XMOS XU208-firmware..
so if someone gets a hand on this firmware, rewrite it a little bit, everybody with a XMOS XU208-USB-bridge could eventually benefit from this and everyone with such a USB-Bridge could get DSD512/768khz..(with an ES9028Q2M).
but i guess we have to wait for that/its just only an idea 😉

Link-tip: Audiophonics.fr

Audiophonics.fr has wonderful pricey DIY-things, like cheap DC-DC Converter Module 3.3-13V to +/-15V by example but also a lot of DIY-Hifi-equipment..found it originally by their ES9028Q2M Audiophonics-made „Audiophonics I-Sabre ES9028Q2M TXCO„-HAT..
can be also expensive, u have to look exactly, but as said also relatively pricey things and they resident in the EU->means shorter shipping-times (for me)..
interesting site..😉
