My Daddy Kenji named me 'Hana Gontakureno Dorosky'.
(  Hana means a flower in Japanese,
  Gontakureno means a hoodlum,
  Dorosky means being crazy about mud. )
When I find muddy water,
I lose my sane, and mad on mud, then  I'm muddy all over.
After come to myself, I feel sorry and return to Daddy.
Daddy wash me, with mumbling.

Hana

My name is Hana, I'm 8 years old.
I introduce my family.
















This is my daddy, my neighbor.
He is almost 13 years old, but he is in good health.

My mother and me, when I'm a baby.
She passed away 5 years ago, I miss her.

It snowed the day before yesterday, in Hiroshima.

Walking around with my dogs,
Hana was very pleased that snow lay.

My Dogs

They are my dogs.

They are my dogs.

STM32_USB_FS_Device_Lib_V3.1.0

CANとUSBを同時に使うためSTM32F10XCLに飛びついたが、STM32_USB-FS-Device_Lib_V3.1.0 で挫折中。
stMicroのライブラリは使って細かいバグはあっても基本的には良くできていたので全面的に信頼していたんだが、
これはハードのことに詳しくない癖にビットフィールドを使って妙に格好付けるような人間が書いたんじゃないかとだんだん腹が立ってきた。
今日stMicroのコミュニティを見たら４月の予定でBugfixしたライブラリを出しますとのアナウンスがあった。
とりあえずは半二重で試作品も使えるようになったので４月まで辛抱強く待つことにする。

STM32_USB-FS-Device_Lib_V3.1.0

STM32_USB-FS-Device_Lib_V3.1.0
ライブラリを使ってEPINとEPOUTの割込が重なるとエラーが発生し通信が出来なくなるので、
RAMにトレース用リングバッファを設けて割込の状態を記録してみた。
怪しい部分を見つけたので誰かの参考になればと思って晒しておく。

USB

STM32F105RCTへのUSBドライバポーティングで壁にぶちあたって一週間が経つ。
コミュニティの反応などを見るとどうもUSB_OTG_FS用ライブラリ3.1.0のバグではないかと思われるのだが、stMicroの技術サポートは英語対応のみなのでレポートを英語で書いてみた。

Bugs in USB OTG library?

I am testing for the motor drive board using STM32F105RCT using USB, the following problems have occurred.

(Test situation)
  Via EP1IN, the data  is continuously sent from a board to PC.
　And via EP2OUT, it sent a character at a time to a board from PC , the next error will sometimes occur.

(State of an error)
The EP1IN packet exceeding 64 bytes occurs, and it becomes impossible to send data to PC from a board after it.
An EP2OUT packet is then sent to a board normally from PC.
At STM32F, it is "usb_istr.c. : Since  IN Endpoint interrupt(diepint.b.emptyintr == TRUE)" has occurred continuously,
 it is in the state where a main loop cannot be performed.

Although USB communication was completed very simply using the stMicro offer library in STM32F103 series,
 is there still any bug in the library for USB_OTG_FS?

(Test environment)
 CPU              : STM32F105RCT6
 Compiler        : GCC4.4.2USB
 USB library     : stMicro   STM32_USB-FS-Device_Lib_V3.1.0  included in um0424
 Test Program :   Changed a part of Virtual_COM_Port according to the board.


Application: Maxon ECFlat45 Motor Drive Board
